I want to know if there is any Linux distribution with PREEMPT_RT kernel patch?

If not, is there any good tutorial on how to patch and compile a kernel with RT patch and how can I create kind of a dual boot of default Arch Linux kernel and my own kernel to boot into the same Linux instalation?

By the way, checking on my Android phone, I noticed that my Linux is Linux localhost #1 PREEMPT Sat Apr 6 01:32:41 EEST 2013 armv7l GNU/Linux, but I have a custom ROM installed on my phone, but I was wondering, are all Android phones patched with Linux PREEMPT kernel installed?

Edit: so, I have found a distribution with real time kernel called AP-Linux. Haven't tested it yet.

Really, no one? :P – Alko Sep 2 '13 at 7:56

Debian provides the Linux kernel with an applied PREEMPT_RT patch. For example, to install the amd64 version:

# aptitude install linux-image-rt-amd64

Similarly, Ubuntu also provides a respective package in its repository:

# apt-get install linux-image-rt
